django里能用pymysql吗

可以，在Django的settings.py中设置DATABASES选项，将ENGINE项设置为'django.db.backends.mysql'，将NAME、USER、PASSWORD、HOST、PORT等项设置为连接MySQL数据库所需的信息。然后在项目中可以引用pymysql库进行操作。具体实现可以参考以下代码：

# settings.py

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'mydatabase',
        'USER': 'mydatabaseuser',
        'PASSWORD': 'mypassword',
        'HOST': 'localhost',
        'PORT': '3306',
        'OPTIONS': {
            'charset': 'utf8mb4',
            'use_unicode': True,
            'init_command': "SET sql_mode='STRICT_TRANS_TABLES'"
        },
    }
}

# views.py

import pymysql

def my_view(request):
    conn = pymysql.connect(
        host='localhost',
        user='mydatabaseuser',
        password='mypassword',
        db='mydatabase',
        charset='utf8mb4',
        cursorclass=pymysql.cursors.DictCursor
    )
    with conn.cursor() as cursor:
        sql = "SELECT * FROM mytable WHERE id=%s"
        cursor.execute(sql, (request.GET.get('id'),))
        result = cursor.fetchone()
    conn.close()
    return HttpResponse(result)
